More about S7-1500 function modules and how to choose them

SIEMENS SIMATIC S7-1500 function and technology modules

Technology modules extend the SIMATIC S7-1500 PLC with specialised hardware functions for applications requiring fast or precisely timed signal processing. They are used, for example, for pulse counting, frequency and speed measurement, position detection or drive control.

Depending on the application, TM Count, TM PosInput, TM Timer, TM PTO or the programmable TM FAST module can be used. When replacing a module, it is important to check not only the order number, but also the type of connected sensor, encoder or drive and its configuration in TIA Portal.

TM Count

Modules for high-speed pulse counting and frequency or speed measurement. They are used, for example, with incremental or pulse sensors.

TM PosInput

Technology modules for counting and position detection. They can process signals from RS-422 incremental encoders or SSI absolute encoders.

TM Timer

Modules with time-controlled digital inputs and outputs for applications where precise timing of binary signals is important.

TM PTO and TM FAST

TM PTO is used to control stepper drives via pulse outputs. TM FAST is a flexibly programmable module for high-speed technology applications.

How to choose the right S7-1500 function module?

When replacing an existing module, the safest method is to use the complete SIEMENS order number. When selecting another module, we recommend comparing in particular:

  • required technology function,
  • number of channels,
  • type of connected sensor, encoder or drive,
  • electrical level of input and output signals,
  • required signal processing speed,
  • hardware and firmware version of the module,
  • wiring and channel configuration,
  • compatibility with the hardware configuration in TIA Portal.

Typical S7-1500 function and technology modules

Order number Module type Type / application
6ES7550-1AA01-0AB0 TM Count 2x24 V High-speed pulse counting, frequency and speed measurement
6ES7551-1AB01-0AB0 TM PosInput 2 Counting and position detection using incremental or SSI encoders
6ES7552-1AA00-0AB0 TM Timer DIDQ 16x24 V Time-controlled digital inputs and outputs
6ES7553-1AA00-0AB0 TM PTO 4 Four-channel interface for stepper drive control
6ES7554-1AA00-0AB0 TM FAST Programmable module for high-speed technology applications

TM Count, PosInput, Timer, PTO or FAST?

TM Count is primarily intended for high-speed counting and frequency or speed measurement. TM PosInput is used where position data from an encoder needs to be evaluated. TM Timer provides precise timing of digital signals, while TM PTO generates pulse signals for drive control.

TM FAST is intended for special high-speed applications where signal processing needs to be flexibly adapted. When selecting or replacing a module, we recommend using the exact order number and the required technology function.

New and refurbished function modules from stock

For current SIMATIC S7-1500 technology modules, we primarily check the availability of a new original SIEMENS part. We use an extensive European warehouse network with more than 900,000 industrial spare parts.

This also enables us to source refurbished, older, obsolete or hard-to-find function modules. If you cannot find a specific order number in the e-shop, send it to us and we will prepare a quotation with price and delivery time.

SIPLUS S7-1500 function modules

Selected SIPLUS S7-1500 versions are also available for applications operating under more demanding environmental conditions. You can find them in a separate SIPLUS function modules subcategory.

Frequently asked questions

Is the module order number enough for an enquiry?

Yes. Ideally, send us the complete SIEMENS order number from the nameplate, for example 6ES7550-1AA01-0AB0, and the required quantity. We will prepare a quotation with price and delivery time, usually within 1 hour.

Can you supply a function module that is not listed in the e-shop?

Yes. We also check other technology modules in European warehouses. Send us the order number and we will prepare a quotation based on current availability.

What is the difference between TM Count and TM PosInput?

TM Count is primarily used for high-speed pulse counting and frequency or speed measurement. TM PosInput is intended for position detection using incremental or absolute encoders.

What is TM PTO used for?

TM PTO generates pulse output signals for drive control. When selecting it, the required electrical interface, number of channels and configuration of the specific application should be checked.

Can I replace a function module with another order number?

Not always. The technology function, number of channels, electrical interface, sensor, encoder or drive type, hardware and firmware version and TIA Portal configuration must be checked.

Do you arrange repairs of S7-1500 function modules?

Yes. You can send the faulty module to FOXON. We will arrange diagnostics, repair and subsequent functional testing at a specialised European repair centre with which we have long-term cooperation.
